Thinking about swapping out my freewheel instead to get more speed, going from the 14-28 to 11-28:
https://www.amazon.com/DNP-Epoch-Fre.../dp/B007A8RPUS
According to a gear app I downloaded, it would give me ~4 mph/hr provided I could spin the cranks
If I got the biggest chainring I could buy (58), it looks like ~1.8mph
Only thing giving me pause is it seems the quality of that freewheel is debatable...

Given that silly freewheel costs like a third of what your whole bike cost, I can see the need to get some value out of the purchase, but Shimano quit making 11T freewheels, probably because of reliabilty/durability? DNP is the only one that covers that niche.
I bought two 11-30 DNP's for our folders in 2017. They were $29.46 then. Up $10 in two years. Wow. One has a 52T chain ring, and the other is 46T. I need to upsize the latter.

Factory gearing are use from factory for good reasons and there are plenty other bikes that are more efficient at going faster.
It's hard for me to sustain the tallest factory gearing during my daily commute, simply because traffic pattern doesn't allow higher speed without the danger level going up substantially.
Even with factory gearing, I'm passing cars between mirrors and dodging pedestrians that walks out in front of me without looking.
It's a cheap bike, I keep OEM items unless related to personal fit or comfort.. speed isn't a priority for folding bikes, likely it's not designed to perform at higher speed regularly or safely.

Have you been happy with the quality of those freewheels? Seems so me people have been disappointed with quality...

I have a Steel Dahon that cost around $80USD $150USD (the frame probably weighs twice as much though)
I still ride it fairly often, its been so trouble free that its quite boring, its great for unexplored routes though.
Edit: $80 is crazy cheap for a new folder, I'd buy 10 and flip them for double the price if I had storage space.

Rides being more dangerous at higher speed is universal, not just to individual.
If a bike is designed & geared at the factory to be ridden at slower pace, changing the gearing for faster riding is simply inefficient and dangerous.
Like I said in my previous post, there are plenty of other bikes that can go faster more efficient.
Folding bikes are just not meant (and inefficient) to be ridden at sustained higher speed, that's not limited to each their own.

I've upgraded less expensive folders before,... And I've done so with the blessings, and even assistance, of bike company reps, as well as bike company owners. You saying it's dangerous and innefficient is your personal opinion.
As for riding a folder at higher speeds,...there's nothing wrong with it. If a person is capable of doing so, so be it. Again,...what you stated is your personal opinion,...not a fact. This forum is all about updating and upgrading.

^ How fast? ^
I wouldn't consider my cheap folder to be dangerous at all, as long as the tires stick, it can be ridden just as fast as any other bike. (on smooth pavement)
Sure its not as efficient as a traditional 700C bike, it can fit in a suitcase, and for me that is a worthy trade off.
It has paid for itself many times over in terms of baggage fees that most airlines charge for bicycles.

Great to see some voices of reason. Changing gearing is not going to render the bike dangerous at all; it will now be more capable for its intended use / terrain.

GRandom pointless ramblings. First it’s dangerous to change gearing and now it’s because one doesn’t have the strength or endurance for stock gearing.
Why are cars outfitted with more gears these days? Why don’t they just make more powerful motors?
Because efficient gearing for the terrain/speed/cadence you ride makes sense. You can use a single speed to ride the mountains, but that rider with “no legs” but gears will catch and surpass you eventually.

If you are constantly running our of gears, then you're riding the wrong bike.

Sorry,...your opinion is just that,...opinion. This entire section of the forum is filled with people modding their folders,...who are you to pass judgement? Really,...

As if anyone is looking for a folding bike to start riding in local training rides to go fast?
Going fast is not a priority when someone buy a folding bike, especially at below $100.
If you want to convert a 20" wheel folding bike to ride faster with more energy spent than other bikes, go right ahead...
Right tool for the right job, there are simply far more choices to go fast than a cheap folding bike.
All above are just simple facts.. not just my opinions.

This section thrives on modification,...you need to accept that. If not, move on. 99% of us like to mod our bikes. And this is for folding & non-folding bikes. I've modded all my bikes,... Even swapping a seat is deemed a modification.

Spicyfoodlover, I believe most of the DNP complaints come from riders that go far and fast on their bikes. These are the same guys who wear out chains. Who knows, mine could outlast me.

DNP = DO NOT PURCHASE
Machining sucks, causing excessive drivetrain vibration, and the pawls skip.
This is my experience with three of their freewheels so far.

Freewheels are cheap, Shimano units are reliable, easy to find, and easy to replace if you have the proper tools. (a freewheel tool, a vise, or a wrench with a pipe on the end)
Also, it could be I just had a bad batch of DNP freewheels, however, I won't be purchasing any more.
Better still, get a cassette hub wheel, and use whatever gearing you like.

You have a great nice bike. It might be cheap as you say but it has plenty of quality unlike some other cheap bikes that actually have bad components. This has almost all what one would need on a folding bike.
